The Knowledge Project with Shane Parrish

Shane Parrish built Farnam Street into one of the most respected thinking blogs on the internet, and The Knowledge Project is its audio extension. Since 2015, Parrish has recorded over 260 long-form conversations with people who've achieved remarkable things in business, sports, science, and leadership. The guest roster reads like a who's who of high performers -- James Clear talking about habit formation, Morgan Housel on the psychology of money, Bill Belichick on sustained excellence, April Dunford on product positioning, and Home Depot co-founder Bernie Marcus reflecting on building a retail empire from scratch. Each conversation typically runs 60 to 90 minutes, and Parrish doesn't rush. He asks thoughtful follow-ups and gives guests room to develop their ideas fully. The focus isn't on surface-level career advice. Parrish is interested in mental models, decision-making frameworks, and the principles that hold up across decades and disciplines. That's what separates this show from the countless other interview podcasts cluttering the business category. A conversation about investing will touch on cognitive bias. An episode about leadership will veer into philosophy. The connective thread is always practical wisdom -- insights you can actually apply. Parrish also runs a members-only feed with bonus content and ad-free episodes for subscribers. His Farnam Street newsletter reaches over 750,000 people, so guests know they're speaking to a thoughtful audience. If you're the kind of person who marks up books and revisits ideas, this podcast was made for you.
